Cobalt Sucker Rod Guides are designed for use in artificial lift (pumping) wells to eliminate the internal tubing wear caused by contact with the sucker rods. The sucker rod guides minimize costly metal-to-metal contact between the sucker rods and tubing. The guides also function as bearings by centralizing the sucker rods in the tubing string. Even when the tubing buckles during upstrokes, the guides help prevent contact between the rods and tubing. Friction is also reduced, which raises the overall pumping efficiency.

Our unique wrap around rod guide design creates a "double-lock" grip on the sucker rod. That grip is strong enough to prevent slippage in most well conditions. Cobalt Rod Guides are easy and safe to install and remove using our Sucker Rod Guide applicator system. CobaltSPIRAL Rod Guides can also be "Overmolded" directly to CobaltMAX Sucker Rods.

• High resistance to Sucker Rod Guide damage from impact and side loading

• Spiral FlowPass design

• Maximum Sucker Rod Guide Erodible Wear Volume (EWV)

• Sucker Rod Guide Computer Modelling

• Excellent dimensional, thermal and chemical stability

• Polymer formulations for maximum abrasion resistance

CobaltSPIRAL Rod Guides were developed to increase the lifespan of the rod and tubing string. The engineered design combined with unique abrasion resistant polymer technology prevents the rod and couplings from contact with the internal surface of the tubing, which can cause expensive tubing damage and unscheduled well servicing costs… in addition to lost production.

Our ARPMAX polymer technology is formulated for applications with high velocity abrasive fluids, engineered to reduce the pressure differential in the rod guide area, reduce torque and reduce the potential for localized abrasive concentrations below and around the rod guides and couplings.

To avoid rod and tubing wear, CobaltSPIRAL Sucker Rod Guides can be field installed at pre-determined spacing suited to the conditions to prevent the rod and rod coupling from contacting the tubing internal surface. Internal force analysis shows that the sucker rod is subject the axial forces, side loads and internal bending moments with the changes in hole deviation from vertical.

As a result, the stress and wear potential in some well sections can be very high while in other positions the stresses are low (ie vertical sections). Analysis shows that peak sucker rod stress can be reduced by shortening rod guide spacing. .

CobaltSPIRAL Field Installable and/or Overmolded Sucker Rod Guides are the ideal solution for any rod-to-tubing and coupling-to-tubing wear in artificial lift well completions.
